'The side plates equipped withtelescoping binder posts, nf here' Ater niore tully described, tensiblelocking' post and n removable eX- is also grovlded.

As shown in Figs. l and 3, the ends l of the back plate l are bent up atright angles, and the edges lb o' the ends bent inwardly and downwardlyto forni :i Groove to enibiece guide Ll or the irregulzir forni shown inFig. 3 secured to end stiucturnlly forming a part o? tie opposite side,plates These side plates each cons' ola portieri 2 parallel with thebeck gioie and which will be termed the horizontal portion, and n.portion 2b lying` at a right angle thereto und which will be termed thevertical pon tion. ln the rectangular recesses between the side Qortionsoi the Side frame plates and the guide bars ere secured cushion blocks 5by Ineens oi' short heeded studs 6 'formed with internallythreadedsockets engaged by headed screws 7. rhese screws also serve as ameans for securing two poet bers 8 respectively to the opposite sideplates 2, such bars being; further supported near the center ot each bypair of studs .9-9 secured to 'the side plates and having threadedsockets engaged by headed screws lO. The upper edges of the post bersare recurved and lie against the top flanges 22 which extend inwardlyfrom the opposite vertical portions 2b of the side plates 2 between thecushion blocks 5.

Theback frame plate l, adjacent ench end end centrally thereof2 hassecured to it a stud or post il which is i'ornied with :in internallythreaded socket adopted to reeive :t screw l2 by means of which a coverplate 13 is rigidly secured to the back. rhis plate is further supportedby other studs also cured to the beck plate and 'forming pivots forcertain mechanism to be later described. Each end of the cover plate,between the vided with a key.

notches, or slots in the edges On its inner side the hub of the pinion49 is formed with a socket pivotally supporting the outer end of theplunger 46, which eX- tends beyond the disk 47.

ln addition to the telescoping posts 18-19 secured to the post bars 8 otthe trame, l have provided an extensible removable locking post, shownin Figs. 7 and 8. This post consists of a tube 50 in which is arrangedto slide a headed rod 51 pressed by aspring 52 toward extended position.The outer end ot the tube 50 is provided with a head 53 formed with anannular locking groove, and with a key socket arranged to receive thebit 38 of the operating key before mentioned.r This binder post isinserted in registering holes in the side frame members 2`D and postbars 8, and when inserted is retained in place by means of a springpressed locking pawl 54 which is pivoted upon a stud 55 secured to theside .trame member 2b and which engages the locking groove in the head53 of the post. The pawl iscammed aside by the inclined front end of thetube 50 as the post is inserted, and released by inserting and turningthe key, the prongs of the bit of the key Jforcing the pawl out of thelocking groove.

The binder posts 18-19, it may be here explained, are intended to engageopen of the sheets which are used in the binder, while the re'- movablepost 50 is designed to engage holes or pertorations in the sheets forthe purpose of preventing removal by anyone not pro- The operation ofthe binder will readily be understood from the foregoing descriptionwithout detailed explanation. Assuming the binder to be open and thelocking post removed and that it is desired to place a body ot sheets inthe binder and close and lock it, the sheets will be inserted upon thebinder posts and the sides pressed together against the pressure of thesprings 17 to grasp the sheets as tightly as convenient. The equalizingracks will force the sides to come together equally in perfectparallelism, and the ratchet 35a-42a will permit the pinion to rotatewithout moving the pinion 42. The key is now applied to rotate thepinion 3G in righthand direction, and through the pinion 38, worm S9,worm gear 40, and pinions 41, 42 and 35, and connected rank mechanism,the sides may be clamped together as tightly as desired, the pitch otthe worm and proportions of the pinions and gears being such as to avoidany interference or locking up as the sides shitt their positionrelatively to the back plate.

In thus turning the key the pinion 36l will rotate the pinion 49 andratchet 48-47a until the stop lug 47b comes into contact with the lug45a on the release bar 45, after which the teeth 4S will cam the teeth47 a and plunger back without moving the release bar, the plunger springbeing weaker than the spring 44 in the hub of the pinion 42.

The removable locking post may new be inserted and pushed in until itautomatically locks through engagement otl the pawl in the lockinggroove of the post, atter which the leaves cannot be removed or thesidesunclamped by anyone who is not provided with a key.

lVhen it is desired to open the binder and remove the sheets, thelocking post is i'irst removed, and the key then applied to the keysocket of the pinion 36 and turned in the reverse direction, which willVFirst rotate the pinion 49 and ratchet members 48-47 until the lug 47bhas made nearly a complete revolution and come into contact with theother side ot the lug 45ththe pinion and its connections meanwhileslackening the sides somewhat,-atter which a further turning movement otthe key will turn or twist the release bar 45, and its flat fare willcam the pinion 42 downwardly against the tension ot its spring 44, thusreleasing the clutched engagement ot the ratchet members 42a-S5. Thiswill permit the springs 17 to exert their stress and the sides of thebinder will open apart.
